Fatented Aug. 4, 1931 errau STATES PATENT OFFICE NOEL J. POUX, OF IVIEADVILLE, PENNSYLVANIA, ASSIGNOR TO LION FASTENEB INC., OF MEADVILLE, PENNSYLVANIA, A CORPORATION OF DELAWARE SEPARABLE FASTENER Application filed June 6, 1930. Serial No. 459,456.

111 forming separable fasteners involving adjacent edge to edge stringers provided with interlockingmembers it has been common to secure the stringers at the end of the interlocking members with a metallic plate. The present invention is designed to improve this manner of securing the ends of the working portion of the fastener together by a scheme of cross stitching which secures the stringers together securely and forms an abutment, or stop limiting the movement of the common operating slider. Features and details of -the invention will appear from the specification and claims.

A preferred embodiment of the invention is illustrated in the accompanying drawings as follows Fig. 1 shows a plan view of the fastener having the stitched end closure.

on the interlocking members at one edge extending into the cavities of the members on the. opposite edge to form the lock between the members. A slider 8 is' provided with the usual guide flanges 9 and the separating arrow-shaped center 10, this slider operating with relation to the interlocking members swinging them into and out of interlocking engagement. The slider is provided with the usual loop 11 and tag 12 by means of which the slider is operated. So far the parts are of common construction.

A closure at the end of the interlocking members is formed by a series of rows of cross stitching 13, this stitching being preferably formed by long cross stitches embrac ing both ribs, the threads at the top and bottom being preferably connected by locks 1 in the manner of the ordinary lock stitching. A longitudinal line of stitching 15 is preferably provided along the dividing line between the ribs .drawing the cross stitches down into close binding engagement with the the ribs. This stitching in itself acting with the slider makes a very desirable stop for the slider in that the last two interlocking members are held together as the slider does not move down far enough to separate them.- Consequently with each operation of thefastener the opposing series of the members are sure to be in proper relation to be swung into engagement.

I prefer to form steps 26- for the slider at the open end of the fastener. These stops are formed in a manner similar to the cross stitching 13 except the cross stitching is around one rib and extends through the fabric back of the rib. The cross stitching may involve more than one thickness of stitching.- When the slider reaches the closing limit it contacts these masses of stitching and is thus stopped.

In the modified construction shown in Figs. 4 to 8, the parts and stitching is similar to that shown in Fig. l, but a stop plate 16 is arranged between the edges at the end of the stitching. The plate 16 has forked ends 17 straddling the ribs and these forked ends are adapted to engage the guide ribs 9 of the slider and form a stop therefor.

In the structure shown in Fig. 9 there is added to the cross stitches 13, as shown in Fig. '1, a series of longitudinal stitches 19 embracing the cross stitches and at the stop end of the cross stitches. The modification also involves a stop plate 20 having forked 'of longitudinal stitching 25 embrace the cross stitches, these lines of stitches being between the edges and the interposed filler.

What I claim as new is 2+ 1. In a separable fastener, the combination of stringers having opposing series of interlocking members on the stringers adapted to be swung into and out of locking engagement; slider operating the members; and a sewed connection between the edges at the ends of the series of members forming a connection for the stringers and forming a means for limiting the movement of the slider with the slider in position to actuate the end members.
